Custom recipe to get OS X 10.10 Yosemite running from scratch, setup applications and developer environment. I use this gist to keep track of the important software and steps required to have a functioning system after a semi-annual fresh install. On average, I reinstall each computer from scratch every 6 months.
This keeps the system performing at top speeds, clean of trojans, spyware, and ensures that I maintain good organizational practices for my content and backups. I highly recommend this.
I was encouraged to fork this and modify it to my heart's content to match my own needs. Thanks to @kevinelliott
Note: I manage my dotfiles and vimrc with Homeshick. My environment is hyper customized and is not for everyone's taste.
